Glacial Epochs of the Santa Monica Mountains, California

Davis, W. M.

Abstract

The Santa Monica Mountains of southern California are far too low to have been glaciated, but the features of their south-facing coast are believed to record four epochs of sea rise and abrasional advance alternating with three epochs of sea lowering and withdrawal during intermittent coastal upheaval; and these seven epochs of high and low sea level are interpreted as representing the last four Nonglacial Epochs (including the present Postglacial) and the last three Glacial Epochs of the Quaternary Glacial Period.

© 1933 Geological Society of America. Read at the Tulsa meeting of the Society, December 30, 1931, and at the Los Angeles meeting of the Cordilleran Section, March 6, 1931. Manuscript first received by the Secretary of the Society, September, 1932; and in revised form, July 5, 1933. The following pages present the results gained in company with a number of my friends on twenty or more visits to a 30-mile stretch of the Southern Californian coast during the last six years. Various aspects of the problems there encountered have been profitably discussed on the ground with Prof. J. E. Wolff, my former colleague at Harvard University, now resident in Pasadena; with my former student, Samuel Storrow, Harvard '87, now resident in Los Angeles; with H. S. Gale, W. S. W. Kew, R. D. Reed, and H. W. Hoots, geologists of Los Angeles; with U. S. Grant, 4th, of the University of California at Los Angeles and with Edwin Yan Amringe of the Pasadena Junior College; also with several of my recent students, three at Stanford University, H. R. Gale, now with the U. S. Land Office in Montana; W. C. Putnam, now instructor in the Los Angeles Junior College; and G. L. Richards, Jr., and three at the California Institute of Technology; J. H. Maxson, now instructor in that institution; Y. C. Kelley, now teacher in the Los Angeles city school system, and Irving Krick, now meteorologist for the Western Air Express; as well as with many friends in Pasadena. My thanks are tendered to all these companionably associated for transportation and photographs, and for the many helpful observations and suggestions which they have generously placed at my service. I am also greatly indebted to Professor Douglas Johnson, of Columbia University, who, acting as censor for our Society, has critically suggested many changes in my original manuscript, by the adoption of which the article has been greatly clarified and improved. I am especially obliged for several excellent photographs by E. L. Furlong, curator of vertebrate paleontology, California Institute of Technology, and by E. Thompson, photographer, of Los Angeles.
